Effects of Crossover Point Exercise on Vascular Function of Women in Different Menopausal Years

This study looks at how exercise affects blood vessels in women who have gone through menopause. Menopause is when a woman's periods stop, usually around age 50. Women will be put into one of four groups: Early Postmenopausal Exercise (EE), Late Postmenopausal Exercise (LE), Early Postmenopausal Control (EC), and Late Postmenopausal Control (LC). Everyone will do a test to see how well their heart and lungs work by measuring the maximum amount of oxygen they can use. After the test, the health of their blood vessels will be checked. Women in the EE and LE groups will exercise on a bike for three months. All women will have tests before and after these three months to see any changes.

• Study lasts for three months with tests before and after.
• Participants will be divided into exercise or control groups.
• Only women without heart disease and within certain health limits can join.
